Is there an eyepiece in there as well?

No there isnt, and i am begining to see the flaw in my plan and the reason why the idea didnt work so well. In essence I need to focus the image directly onto the chip in the webcam which allows me to use the telescopes focus. This is preferable as I can use the eyepiece also without having to remove any of the camera stuff. However,I may try the afocal method prior to removing the lens from this webcam as I think that this might be an irreversible operation on this model. But also...

The other way is to remove the lens of the camera and then attach the camera to the telescope but without the eyepiece. This is called prime focus. You use the telescope focusser to focus. With a toucam you get high magnifications ie 208x in my 10" reflector

According to the article you referred to, it sounds like the magnification using afocus will be much greater than prime focus? I guess that the magnification level does not go beyond the useful magnification of the scope because afocal has the effect of increasing the focal length rather than trying to increase the eyepiece power alone? According to the article, with my tube length (between camera and ep) of 56mm and using a 10mm eyepiece I would be increasing my focal length to 56/10 X 1325mm or 7420mm Is that how it works? sound a lot.
